The ESBE 81 24V 3P actuator is a rotary actuator for motorised control of mixing/rotary valves in hydronic (heating and cooling) applications. It is designed for simple and reliable valve position control using a 3-point signal. Thanks to its short running time and sufficient torque, it is suitable for standard mixing circuits where a fast control response is required. This variant corresponds to Series 90, designation 91. The ESBE 81 model is being replaced in the ESBE range by the ARA600 (12050200) actuators, which retain proportional control and are intended for the same types of mixing installations.
